Hi,
If you are looking for a simple packaged solution that already
incorporates a database table, then the `alias_db` module is your best bet:
https://kamailio.org/docs/modules/5.3.x/modules/alias_db.html
The number can be translated to a SIP Request URI domain via
alias_db_lookup(), and that domain will of course be consumed when you
forward the request, absent other next-hop overrides.
If alias_db_lookup() returns false, then you can fall back to a
dispatcher election.
The major downside of this approach is that if your intent is to divert
only a small amount of numbers out of your load balancer, this, as all
other database-bound approaches, incurs an unnecessary database lookup
for every single call. However, this is not a significant factor in most
cases. It deserves some attention for very high CPS (Calls Per Second)
operators, though.

Hi all,
im fairly new to Kamailio and currently setting up our new sip-server
systems so, hello everyone!
right now i have a Kamailio SBC which routes all calls using the
dispatcher module to our internally setup application servers (freeswitch).
i just got the idea that we might want specific routing based on
destination phone number in addition to simple loadbalancing.
can anyone point me in the right direction where i should look for
something i can place before the dispatcher routing to route calls based
on some entries in a database like destination number XYZ goes to server
A, number ABC goes to server Z and so on.
Or is there a way to select the dispatcher group id from the database
based on destination number?
best regards
Christoph
